D/W R3W.1562-2Z Bearing Product Overview & Core Advantages
The D/W R3W.1562-2Z is a single row deep groove ball bearing engineered for high precision and reliable performance in demanding applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to efficiently handle radial loads, while the integral shielded (2Z) design on both sides retains factory-applied grease lubrication and protects against contamination, ensuring long-term, maintenance-free operation. This compact and robust bearing is ideal for applications requiring high rotational accuracy and durability.

D/W R3W.1562-2Z Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The rings, balls, and cage are manufactured from stainless steel, providing superior corrosion resistance and making the bearing suitable for harsh environments, including those requiring washdown or exposure to certain chemicals.
- Optimized for Radial Loads: The deep groove raceway and single-row design are precision-engineered to carry significant radial dynamic load ratings (136 lbf), ensuring stable operation under primary radial forces.
- Shielded & Pre-Lubricated Design: The non-contact steel shields (2Z) effectively protect the internal components from dust and debris while retaining the factory-applied grease. This creates a sealed-for-life unit, eliminating the need for re-lubrication and reducing maintenance costs.
- Standard Precision & Clearance: Manufactured to ABEC 1 (P0) tolerance class with CN group radial internal clearance, this bearing offers a reliable balance of precision, running smoothness, and thermal stability for a wide range of industrial applications.
